Review on Dell XPS 15 9550 15-9550 Precision 5510 P56F 1P6KD 01P6KD P56F001 T453X 0T453 11.4V 84Wh 4GVGH Laptop Battery (Not For Models With SSD/HDD) by Brandon Frogge

If you're reading this review you've probably clicked on several different listings for this type of battery and read the small handful of reviews on each. I was in the same boat when I decided to pull the trigger on this particular listing. I'm not a technical person so I can't give you all the technical background on if this battery is performing to spec, but I can say that it is a VAST improvement over my previous factory battery that was dying within 10 minutes of being unplugged. This battery came with clear installation instructions as well as the tools needed for the job. I was able to watch some YouTube vids that made the process crystal clear. This battery did not have the issue with the connecting cord being too long like I read in reviews of other batteries. I followed the instructions to run the battery down and recharge a few times, but it took forever to run the battery down out of the box (playing Netflix with the brightness on 100 and power manager set to max performance) and since then I have had no issues at all with battery life. If you're looking for a battery replacement for your Dell XPS - this one is more than adequate and easy to install with the included tools.
